Re: Venturi Design
The flow spirals down. I have a cut-off elbow fitting on the output of the powerhead, aimed to the side, with no effort to make it be parallel to the inside surface of the tube - not enough room to do anything else. I increased the bubble rate a little bit more this morning -- now it is about where it was with the 29 gallon tank, when it fed a powerhead to make mist. Of course I have two bubble rates, with the bubble counter having smaller bubbles and a higher rate than the bubble rate in the reactor. It still spills small bubbles out the bottom, but not small enough to act as mist.
It may not act like its supposed to, but I get pearling in about an hour now, so it is doing a good job getting CO2 into the water. I think if I put a little air stone on the CO2 feed tube in the reactor I would have a mist system as well as a CO2 dissolving system.
